I don't know why it's looking into ws.jaxws.Hola directory because it doesn't exist! I built it and to check what happens and now the exception is : | Exception in thread "main" java.lang.IllegalArgumentException: ws.JbpmService is not an interface | at java.lang.reflect.Proxy.getProxyClass(Unknown Source) | at java.lang.reflect.Proxy.newProxyInstance(Unknown Source) | at com.sun.xml.ws.client.WSServiceDelegate.createEndpointIFBaseProxy(WSServiceDelegate.java:546) | at com.sun.xml.ws.client.WSServiceDelegate.getPort(WSServiceDelegate.java:292) | at com.sun.xml.ws.client.WSServiceDelegate.getPort(WSServiceDelegate.java:274) | at com.sun.xml.ws.client.WSServiceDelegate.getPort(WSServiceDelegate.java:267) | at javax.xml.ws.Service.getPort(Service.java:92) | at client.JbpmServiceService.getJbpmServicePort(JbpmServiceService.java:52) | at client.JbpmWSClient.main(JbpmWSClient.java:91) | This is right. I haven't got the interface there, I have the class. So, how I have to put the files to this work fine??? Have I to create the jaxws manually to this works fine??
